Resumen
[ES] Desarrollo de una metodología no convencional capaz de lograr la extracción de los metales de interés que
conforman la estructura interna de los residuos electrónicos, permitiendo obtener metales pesados de
elevado valor económico y conseguir dar un aprovechamiento a los residuos electrónicos generados,
llevando a cabo su reintroducción en el ciclo productivo.
La metodología de ensayo que se ha llevado a cabo para alcanzar los objetivos propuestos ha sido la
siguiente:
- Selección de residuo objeto de estudio.
- Reducción primaria del tamaño de residuo.
- Clasificación granulométrica del residuo reducido.
- Separación de las fracciones magnéticas.
- Caracterización metálica del residuo, de manera previa al tratamiento.
- Caracterización de la fracción férrea obtenida tras separación magnética.
- Lixiviación de residuo electrónico con H2SO4 como agente lixiviante.
- Caracterización de muestras de elementos lixiviados.
[EN] The main objective of this experimental project will be consist of the development of a non-conventional methodology that achieve the extraction of the metals that results interesting and are integrated in the WEEE structure. The method will be developed on a laboratory scale. This will allow us to take advantage of the generated electronic waste getting metals with high value and carry out its reintroduction in the productive cycle. The methodology of the trial that has been carried out to achieve the proposed objectives was: - Selection the waste of interest. - Primary reduction of waste size. - Granulometric classification of waste. - Separation of magnetic fractions. - Characterization of the metallic fraction previously to treatment. - Characterization of the iron fraction obtained after magnetic separation. - Leaching of electronic waste with H2SO4 - Characterization of leached elements.
